Who were some other disabled leaders in history like Franklin D. Roosevelt?

I am writing a book on disabled people who went on to do great accomplishments. As the title implies one of the most well known examples of this is Franklin D. Roosevelt, who was diagnosed with parapelgic polio. I have done a lot of research on this subject for my book. Some other examples of disabled leaders include Joseph Merrick, who was elected mayor of his city. Do you know any other examples of people with disabilities who became leaders (such as mayors or presidents, mostly leaders in civil service and politics) in history?
